Abstract

The present invention relates to a preparation for use in animal feed. The preparation comprises sorbic acid and at least one bioavailable β-glucan and also if appropriate a carrier and a further acid. In addition, the invention relates to the use of the preparation alone in feeds or in a mixture with other feed additives for improving the hygiene state of the feed and for growth promotion in farm animal rearing.

Claims

exact text as granted — not AI-modified
1 . A preparation comprising at least one bioavailable β-glucan and at least one of sorbic acid and a salt of sorbic acid.  
     
     
         2 . The preparation as claimed in  claim 1 , wherein the bioavailable β-glucan is produced from yeast cells, cereals, fungi, lichens or algae.  
     
     
         3 . The preparation as claimed in  claim 1 , wherein it comprises about 5 to about 95% by weight (based on the preparation) of bioavailable β-glucan.  
     
     
         4 . The preparation as claimed in  claim 1 , wherein it additionally comprises a carrier.  
     
     
         5 . The preparation as claimed in  claim 1 , wherein the preparation comprises at least about 5% by weight of sorbic acid.  
     
     
         6 . The preparation as claimed in  claim 1 , wherein it comprises about 10-50% by weight of sorbic acid (based on the preparation).  
     
     
         7 . The preparation as claimed in  claim 1 , wherein it additionally comprises one or more acid or acids different from sorbic acid or a salt or salts thereof.  
     
     
         8 . The preparation as claimed in  claim 7 , wherein the acid different from sorbic acid or a salt thereof is selected from the group consisting of: formic, acetic, propionic, butyric, valeric, isobutyric, trimethylacetic, isovaleric, 2-methylbutyric, hexanoic, succinic, adipic, fumaric, malic, tartaric, citric, lactic, ascorbic, glucanoic, amino, phosphoric, hydrochloric, sulfuric acid and salts thereof.  
     
     
         9 . The preparation as claimed in  claim 7 , wherein the acid or acids different from sorbic acid or a salt or salts thereof is or are present in the preparation in amounts of >0 to about 40% by weight (based on the preparation).  
     
     
         10 . A feed which comprises a preparation as claimed in  claim 1 .  
     
     
         11 . A feed additive which comprises a preparation as claimed in  claim 1 .  
     
     
         12 . The feed as claimed in  claim 10 , wherein it comprises about 0.5-12.5% by weight (based on the feed) of the preparation.  
     
     
         13 . A method of making an animal feed or feed additive which method comprises converting a preparation as claimed in  claim 1  into an animal feed additive or feed additive.  
     
     
         14 . The method as claimed in  claim 13  for pig growing and finishing.  
     
     
         15 . The method as claimed in  claim 13  for rearing of breeding sows.
